The Apex NP600 Rangefinder White is designed specifically for disc golf. Using a 905-nanometer class 1 laser to measure the distance between an object and the rangefinder. This is ideal to determine the distance between yourself and the disc golf basket, or any other target on the fairway. This can also be used as part of course design: providing accurate measurements of distances from possible tees to targets. Three different units of measurements, it can deliver the distance in yards, feet, or meters. The biggest difference between this model and the NF600 is that this model has a rechargeable battery and comes with a charge cable. It also features updated housing and is white in color. The NP600 has multiple modes to give you the most accurate measurement. These are the modes it features: 1. Slope Distance - default mode, measuring distances between an object and the rangefinder 2. Vertical Distance - measures the distance, elevation difference, and the angle 3. Horizontal Distance - measures continual slope distance, angle and horizontal distance 4. Speed Measurement - measures the speed of an object (moving toward or away from the rangefinder) 5. Height Measurement - measures the height difference between two objects 6. Closest and Farthest - measures the distance of several different objects; displaying the closest or the farthest 7. Distance Compensation - measures the recommended throwing distance to an object (the distance may be 300' but up hill, which will feel more like 350' throw thus it will suggest 350') 8. Storage - this will show the last 20 readings you have taken
